Metrohm AG products

The 2035 Process Analyzer for Potentiometric Titration and Ion-Selective Measurements performs analyses with dedicated electrodes and titrants. Additionally, this version of the 2035 Process Analyzer is also suitable for Ion-Selective Analysis using Metrohm high performance electrodes. This accurate standard addition technique is ideal for more difficult sample matrices.

The 2035 Process Analyzer for Photometric Measurements includes a compact photometer module which is stable over a large concentration range, and is thermostated with stirrer capabilities. This analyzer is offered with two options: a cuvette system or a fiber optic dipping probe. The cuvette system is compact in order to reduce reagent consumption, yet it offers a long optical path length for high sensitivity. The fiber optic immersion probe broadens our application range substantially by making the accurate measurement of high concentration samples simpler through the use of internal sample dilution steps and a smaller light path than the cuvette system.

The 2035 Process Analyzer for Thermometric Titration performs automated titrations with a fast-responding, highly sensitive temperature sensor. Instead of the electrochemical potential, the endpoint is determined by enthalpy, i.e., by change in temperature of the solution during the titration. Thermometric titration is by far the most robust titration method available on the market and is excellent for 24/7 online process applications, such as the monitoring of etching baths. No sensor calibration is necessary, and less cleaning steps are needed. Rapid analysis is possible with this technique; acid mixtures, e.g., can be analyzed in less than three minutes.
